We cannot continue to let systems loose in the wild without any concern for how we will deal with them at a later time. Two decades ago, Richard Gabriel coined the idea of software habitability. Indeed, given that engineers spend a significant part of their active life inside software systems, it is desirable for that system to be suitable for humans to live there. We go further and introduce the concept of software environmentalism based on a simple principle: Engineers have the right to build upon assessable systems and have the responsibility of producing assessable systems.
